Race son going to van (7)
I believe the answer is:
scamper
'race' is the definition.
(thesaurus)
'son going to van' is the wordplay.
'son' becomes 's'.
'going to' is a charade indicator (letters next to each other).
'van' becomes 'camper' (I've seen this before).
's'+'camper'='SCAMPER'
(Other definitions for scamper that I've seen before include "Skip around" , "Run with quick light steps" , "Skip about briskly" , "Run about briskly" , "Run along quickly" .)
